' UNITED STATES LEONARD L. ELDBIDGE, OF SAN ANTONIO, TEXAS.

BUILDING CONSTRUCTION.

Application led May 28.1923. Serial No. 641,936.

To all whom t may concern:

Be it known that I, LEONARD L. ELDRIDGE, citizen of the United States, residing at San Antonio, in the county ofBeXar and State of Texas, have invented certain new and useful Improvements in Building Construction, of which the following is a specification.

This invention relates to new and useful improvements in building construction.

The object of the invention is to provide means whereby a re-inforced lire proof wall may be constructed in a simple and practical manner at a reasonable expense and without the services of highly skilled labor.

Another object is to provide u-nits in the form of vertical slabs which m'ay be assembled in a substantial and expeditious manner to form a wall which may be easily linished and ornamented.

A further object ofy the invention is to provide T-shape slabs provided with projecting re-inforcing means and assembled` so that the projecting re-inforcing means is received in vertical joints between the edges of adjacent slabs and cemented, whereby the slabs are bonded together on both sides oi the wall.

Certain features of my Letters Patent issued on April 26th, 1921, for building construction are used in this invention, but no separate claim to the same is herein made.

A construction designed to carry out the invention together' with other particular features of the invention will be hereinafter-described. .l

The invention will be more readily understood from a reading of the following spebification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Fig. 1 is an isometric view of a corner of a w. l constructed in accordance with my inrention, portions of the wall being omitte Fig. 2 is a horizontal cross sectional view of the wall,

Fi 3 is an enlarged crosssectional view showin the manner of setting a. window frame 1n the wall, v Fig. 4 is a plan'view showing the cap lacing, and Y Fig. 5 is a vertical sectional view with a Hoor joist in place.

In the drawings the numeral 10 designates a base wall or under-pinning of suitable di- The slabs have their tongues 13 extending beyond their faces at each end to form lugs 15 and 16 respectively and the .channel 11 has a width substantially equal to the depth of the tongues. The slabs are placed on eachv side of the wall with their'tongues directed inwardly in alternate relation and spacing the slabs apart. This forms a hollow wall of substantial construction.

The slabs are suitably reinforced with a longitudinal angular element 17 preferably formed of large mesh wire fabric. but which may be of any suitable material. The reinforcing element is made to project from the outer edge of each tongue 13 and is received between the bevelled edges 14 when the slabs are assembled. The projecting portions, of said elements are of such length as to terminate in the V-shape recesses so that vthey may be concealed when the recesses are filled.

The slabs are made comparatively thin and of such dimensions as togbe readily handled by one man. A slab ten inches wide and ten eet long has been used suocessfuli but the dimensions may be varied tqmeett e building conditions. The slabs are set up on the base 10 with their lugs 15 in the chan# nels 11. The tongues 13 space the slabs apart and also form vertical air spacesin thev wall. 'Ihe base extends beyond the outer faces of the slabsto form a water-table and also extends beyond the inner faces to provide a ledge on which floor .joists 18 may rest.

Shallow pans 19 arefplaced between the lugs 16 vat the top of the wall to cover the spaces between the tongues. Tie rqds20 are laced around the lugs above thel pans. A

aol

cap 21 is formed by suitably molding concrete or other plastic material Hush with the faces of the slabs and the tops of the lugs, whereby the lacing is embedded and the top ofthe wall bonded. The pans support the cap and prevent filling of the air spaces.

Cement or equivalent .material is troweled into the Vshaped recesses 14 to form joints in which the projections of the re-inforcing elements 17 are embedded and bonded. The two sides of the wall are bound together by the joints and the latter when finished give the slabs a smooth outer surface, which may .be

lastered or otherwise covered. If desire concrete or the like may be poured into the channel 11 between the lugs 15 before. the pans 19 are placed, whereby the slabs are tied to the base.

The slabs when set on the base 10 will with the cap 21 give a height suitable for a one story building. For wlndows and doors shorter slabs may be cast and set above and below the same. .In Fig. 3 I have shown one side 22 cfa window frame fitted into one of the slabs against the tongue 13 thereof. A joint 23 is formed with the bevelled edge 14 ofthe inner slab and one edge of the frame-is embedded in said j oint. The

inner side of the wall is plastered and the casing 24 nailed to the frame.

Various changes in the structure as well as modifications and alterations may be made within the scope of the appended claims.

WhatI claim, is:

1. In a building construction, a hollow wall including a plurality of oppositely arranged slabs formed -T-shaped in cross section, T-shaped re-inforcin elements einbedded in the slabs and projecting from the vertical edges of the tongues, the projecting portions of said elements being received in the Space between the opposed slabs and cemented therein to provide the sole bonding` means for said projecting portions of the reinforcing elements.

2. A re-nforced building slab T-shaped in cross-section. and having its vertical edges along its face portion beveled, a metallic T- shaped re-inforcing element embedded in the slab and having a vertical portion projecting from the outer edge o the tongue of the slab, thebeveled edges of the slab being free from projections of-the reinforcing recesses of the slabs on the opposite sides of the Wall and cemented therein, to provide bonding means in said recesses for the slabs.

4. A reinforced building slab T-shaped in cross-section and having its vertical edges alon its face portion beveled, a foraminous rein orcing element embedded in the slab vertically thereof and T-shaped in crosssection, the intermediate ortion of the reinforcing element exten 'n through the tongue of the slab and projecting from the outer vertical edge of said tongue along a substantial portion thereof.

5. In a building construction, a hollow Wall including a plurality of. o-ppositely arranged slabs formed T-shapcd in cross-section, the 'adjacent vertical edges of the slabs being beveled on the faces thereof to form V-shaped recesses at the joints between the slabs, and T-shaped foraminous reinforcing elements embedded in the slabs and projecting along the vertical edges of the tongues and extending into the recesses, and cement filled in the recesses and in which the projecting portions of the reinforcing element are embedded to bond the wall.

In testimony whereof I aflix my signature.

LEoNARD L. ELDRIDGE.
